The 406 ELT Emergency Location Transmitter

Commercial aircraft are fitted with several portable ELT (Emergency Location Transmitter) devices, which when triggered transmit a distress signals and aircraft information on the 406 MHz search and rescue frequency (as well as the 121.5 MHz and 243 MHz range).

ELT's can be manually or automatically operated and it is a requirement that air crew are trained in the operation of ELT's and become familiar with their use in the training hall.

In operation an activated ELT transmits aircraft and operator information to monitoring satellites for the purposes of providing search and rescue information. An ELT does not provide information specific to the flight itself and should not be confused with the aircrafts FDR (Flight Data Recorder) devices.

For training purposes Cabin Crew Safety offers a range of training representations for common models of ELT's that are in service with airlines and operators worldwide. These match the appearance, weight and operation of the ELT in every way but do not transmit emergency signals, meaning air crew can safely train in handling as well as operating the device.

Popular models of training ELT's are:

• Honeywell Rescu 406
• Kannad 406
• ELTA ADT 406

In the event that no training model is available operational ELT's can be decommissioned and converted to training units. This should however only be undertaken by experienced operators, trained to undertake such work and who are familiar with the requirements of owning, operating and registering ELT devices.
